An Argentine court has sentenced a rock musician to 22 years in prison for sexually abusing minors.

The court ruled Friday that Cristian Aldana was guilty of abuse in four out of seven cases where he was accused. Authorities say the abuses took place from 2001-2008. At the time the victims were 13 to 18 years of age.

Some of the victims were present at the courtroom. They yelled out: "We will no longer remain silent!" when the sentence was read.

The case began two years ago and has since triggered an avalanche of accusations against other musicians in Argentina.

Aldana was the lead singer and guitar player of the Argentine rock band "El Otro Yo", or "The Other Me." He says he has committed no wrongdoing.
